Fujitsu Airstage J-II - Capacity Compensation Coefficient

CAPACITY COMPENSATION COEFFICIENT6.
COMPENSATION COEFFICIENT OF PIPE LENGTH

The tables give the compensation coefcient of pipe length owing to installation position (pipe
length, height difference). Pipe length and height difference are the length and the height
difference between outdoor unit and indoor unit.

(HEATING OPERATION)
To take the effects of accumulated frost and defrosting operation on heating capacity into
consideration, the capacity of outdoor unit should be corrected by compensation coefcient
shown in the table below.
